Describe the update

Updates in https://github.com/geoschem/integrated_methane_inversion/pull/245 created a circular depenedency between the IMI preview and the prior simulation as documented in https://github.com/geoschem/integrated_methane_inversion/issues/253. This can be avoided by restoring the use of archived HEMCO standalone output in the generation of the state vector. Use of the HEMCO prior emissions have been removed from the state vector scripts.

New HEMCO standalone simulations have been performed archiving annual mean emissions for 2023 for 0.25x0.3125, 0.5x0.625, 2x2.5, and 4x5 degree global grids. These can be found in the GEOS-Chem data path HEMCO/CH4/v2024-07/HEMCO_SA_Output.

@nicholasbalasus @laestrada Just a heads up that I have removed the offset code for logitude in make_state_vector_file.py originally implemented in https://github.com/geoschem/integrated_methane_inversion/pull/182. It's no longer needed now that we're using updated HEMCO standalone output.
